Maybe MWI does. I still don't get how MWI explains locality and quantum entanglement in the quantum teleportation experiments.
An hour ago, after my students had finished working through the details of quantum teleportation, I explained a modal (many-worlds) interpretation of the algorithm. There are quite a few other folks here who could explain MWI to you as well.
First, though, you'll need to stop thinking you already know it all. Then you'll need to learn enough basic quantum mechanics so you can perform calculations on those quantum states whose relevance to physical reality you have been denying.
But more to the point: isn't MWI an attempt to preserve particles as fundamentally physical things obeying classical laws of physics?
No.
Also, you forget one thing. Copenhagen is based on what we observe without adding things we do not. MWI is based on adding a huge new factor, a gazillion alternate universes.
As we have seen, your personal Copenhagen interpretation adds all sorts of things that are not really implied by observation. As for MWI, you don't have to believe all of those alternate universes actually exist (although there may be some metaphysical advantages to believing they do).
So if someone says QM shows this. It's not really "interpretation" as you suggest, and they are typically talking about the Copenhagen understanding of what is happening; that is no hidden variables, no alternate universes, etc,.....just what the experiments show.
If all you care about is what the experiments show, then you shouldn't be talking about the Copenhagen interpretations. You should be talking about the Born rule, unitary operators, and other mathematical/scientific stuff.
The main reason for MWI is the results appear to violate basic principles of physical reality. The simplest explanation is to just accept the evidence indicates particles are not strictly physical in the first place.
The experimental results violate EPR's personal conception of physical reality. That means their concepts were flawed in some way. There are several different ways to repair their concepts.
When you're just talking about your own personal metaphysical beliefs, no one will care how you choose to pretend your thinking has advanced beyond Einstein's.
When you proclaim that your metaphysical beliefs are scientific, or that your own favorite variation of the Copenhagen interpretations is the only possible metaphysics, then you're flat out wrong and will likely be called on it.
By the way, you have provided absolutely no scientific evidence for Intelligent Design or Creationism.
